The good old saying, that it never rains but it pours, has received additional illustration in the appearance within a very short time of two lives and one memoir of the great Irish agitator, the late Daniel O'Connell. The latter, it is true, is a mere sketch, intended only as an introduction to a collection of ten or twelve of the most noteworthy speeches of that distinguished man, judiciously selected from hundreds which, as a lawyer, politician, and parliamentary debater, he had delivered in the course of a remarkably busy life, extending over nearly half a century. In this regard, if in no other, it will be found interesting and useful to those who have not leisure or inclination to study the history of his career in detail. Of Mr. Luby's work, published originally in parts, many of which we have carefully perused, we have little to say. It is evidently written in haste, loosely, and without due regard to the canons which are generally supposed to govern composition and narration. There are no facts or incidents in it bearing on the public or private life of O'Connell that are not already well known to every person of ordinary intelligence, and which have not been better and more lucidly presented to the public years ago. It has the demerit, also, of being altogether too discursive, not to say blatant, in style, and the author is too constantly wandering away from his subject to matters quite disconnected from the actions and peculiarities of his hero. Judging from this production, Mr. Luby seems to be a very unfit person to portray the genius, aims, and designs of the great Irish popular leader, lacking as he does that earnest sympathy which should exist between the biographer and his subject, as well as that judicial and philosophical insight into the secret springs of human action which, while recording patent facts, can comprehend and elucidate the true motives, designs, and probable results of the deeds related. Such has ever been considered the real end of biographical literature.
